I have heard that you can upgrade a 1040ST to 4 Meg by swapping the
256K RAM's out and putting in 1 Meg RAM chips. Anyone know if this is true?
Also, is there any difference in external expansion connections on the
1040 vs the 520?

To answer my own question, it is true according to the interview in
Byte magazine, so I'll post another question:
The upgrade of the 1040ST to 4 meg involves swapping the 256K RAM's
to 1 Meg. The 1 Megs have two more pins which the article said could
be bent out. DO they need to be connected to something (like more
address lines)?. Also, is there any reason this same trick cannot be
done with a 520 (using piggybacked 1 Meg chips)?
